RDL Consumer Input Jacks-Stereo-Black - DB-CIJ3D

Product Overview

The RDL DB-CIJ3D is a Decora-style wall plate input module that converts stereo unbalanced line-level signals to stereo balanced outputs for direct connection to professional audio distribution equipment. Designed for permanent commercial AV installation, the unit accepts consumer source signals from either dual RCA phono jacks or a 3.5mm stereo mini-jack on its front panel, then delivers transformer-isolated balanced output via a rear-mounted detachable terminal block. The DB-CIJ3D is a standard solution for conference room AV integration, classroom audio systems, and any fixed installation where a laptop, media player, or consumer device must interface with a professional rack-mounted amplifier, DSP, or mixer. Its Decora form factor allows it to drop directly into standard single-gang electrical boxes, keeping the installation clean and consistent with other wall controls.

Product Description

The RDL DB-CIJ3D provides stereo unbalanced to balanced conversion at the wall plate level, eliminating the need for outboard interface boxes or additional rack equipment in installations where source signals originate at a fixed location. The front panel includes two gold-plated RCA phono jacks for left and right channel input alongside a 3.5mm stereo mini-jack, giving users flexibility to connect either component-style cables or the standard laptop and mobile device audio output. Both input types feed transformer isolation stages that handle hum cancellation by breaking ground continuity between the consumer source and the professional audio system downstream. The balanced stereo output appears on a rear-mounted detachable terminal block, which accommodates standard wire runs to equipment racks or in-wall structured wiring infrastructure. The unit performs the unbalanced to balanced conversion passively with no gain, preserving signal integrity and keeping the noise floor of the downstream system unaffected by the interface stage. The output is rated to drive equipment with input impedance of 10 k-ohm or higher, which covers virtually all professional DSP inputs, mixing consoles, and amplifier input stages in commercial AV applications. The DB-CIJ3D is available in a Black (DB) finish; the same module is offered in White/Gray (D-CIJ3D) and Stainless Steel (DS-CIJ3D) finishes to match different wall plate systems. When specifying a Decora wall plate audio input for conference room, classroom, or hospitality AV integration, the DB-CIJ3D provides a compact, code-friendly installation that handles the consumer-to-professional signal interface at the source location.

Key Features

• Decora Form Factor — Fits standard single-gang electrical boxes for a flush, professional wall plate installation consistent with other low-voltage controls.
• Dual Input Options — Front panel provides both gold-plated RCA phono jacks (stereo) and a 3.5mm stereo mini-jack, accommodating a range of consumer source devices.
• Transformer Isolation — Isolates the unbalanced consumer input from the balanced professional output, breaking ground loops and eliminating hum at the source.
• Stereo Unbalanced to Balanced Conversion — Converts both left and right channels from unbalanced line level to balanced line level in a single module.
• Detachable Rear Terminal Block — Balanced stereo output connects to system wiring via a removable screw terminal block, simplifying field termination and future serviceability.
• Passive Signal Path — No power supply required; no gain is introduced, maintaining signal transparency and avoiding additional noise sources in the chain.
• 10 k-ohm Minimum Output Load — Compatible with all standard professional audio input stages in commercial AV equipment.
• Multiple Finish Options — Available in Black (DB), White/Gray (D), and Stainless Steel (DS) to match architectural requirements of different installation environments.
